)

public:
GdPictureStatus SetBCSG( 
   int ImageID,
   int Brightness,
   int Contrast,
   int Saturation,
   int Gamma
)

Parameters

ImageID: GdPicture image identifier.
Brightness: Brightness adjustment between -100 and 100.
Contrast: Contrast adjustment between -100 and 100.
Saturation: Saturation adjustment between -100 and 100.
Gamma: Gamma adjustment between -100 and 100.

A member of the GdPictureStatus enumeration.

Example

Adjusting the Brightness, Contrast, Saturation and Gamma in an image and saving as a png.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", false);
    gdpictureImaging.SetBCSG(imageID, 20, 20, -20, -20);
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
